1. After sending the superagent request, process the data in the background, and then choose whether to redirect based on the results but it always fails.
2. The code is as follows:

//superagent请求
 request.get(`/allStudios`)
                .end((err,res) =>{
                    next({type:'ALL_STUDIOS',content:res.body})
                });

//后台处理
router.get('/allStudios',(req,res,next)=>{
    Studios.find({},(err,data)=>{
        if(req.headers.cookie){
            res.send(data);
        }
        else {
            res.redirect(302,'http://localhost:3000');
        }
    })
});

3. The result is that there is no way to implement redirection

Please help me solve it, thank you!
